Answer:
Knowledge Acquisition Facility.
Explanation:
The power and effectiveness of the Expert System is equal to the quality of the knowledge it contains. The knowledge has to deal with high complexity and apply the best judgement. collection of expert knowledge is very important and involves the collecting information about a field usually from an expert. This information is stored in a computer program stored as a knowledge base.
Knowledge is always updating so it also very important to keep it up to date and it is done by Knowledge Acquisition Facility.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Answer:
quicksort
Explanation:
There are many types of asymptotically efficient sorting algorithms that can be used but one of the more commonly used for large data lists would be quicksort. This is a sorting algorithm that focuses on choosing a value from the list and working around that value in order to sort the data piece by piece. For larger data sets this method is widely used due to its speed and efficiency which is exactly what Martha needs in this scenario.
